Complexo Metamórfico da Foz do Douro

The rocks of the Coastline from Oporto are the oldest which outcrop in Portugal and constitute a geological heritage of high scientific interest-didactic, the Metamorphic Complex of Foz do Douro, classified as Municipal Natural Heritage. In April 2005 was created a thematic route for dissemination of this designated heritage by "Geological Tour of Foz do Douro", signaled with nine panels of information addressed to the general public.
